Over time, your vehicle’s essential fluids, including transmission, brake, and power-steering fluids, lose their ability to clean, cool, lubricate, and flow freely, potentially leading to problems such as transmission overheating and/or failure.

Vehicle fluid-exchange services may help:

* Improve vehicle performance

* Extend the life of your transmission

* Restore fuel system efficiency for optimal fuel economy

* Reduce harmful emissions

* Prevent future costly fuel-system repairs

How often should I have my vehicle’s fluids flushed?

Your brake fluid, power-steering fluid, and transmission fluid levels should be checked and topped off at every oil change. Additionally, fuel system flushes should generally be performed annually or every 15,000 mi (24,000 km) while automatic transmission fluid flushes are recommended every two years or 24,000 mi (40,000 km).

You may consider scheduling a fluid-exchange service sooner if you notice any of the following:

* Fluid stains in your driveway or parking spot

* Frequent fluid top-offs required

* Dashboard warning lights come on
